Abstract
A suspension type hydraulic support for the coal mine roadway end comprises two external top beams, middle top beams, external top beam support columns, middle top beam support columns, a bracket and a longitudinal push oil cylinder. The two ends of each external top beam are supported via the corresponding external top beam support columns. The two ends of each middle top beam are supported via the corresponding middle top beam support columns. The bracket which is a rectangular frame is arranged on the lower portions of the middle top beams. The bracket is connected with the middle top beams through bracket suspension components. Longitudinal moving guide sleeves are mounted on the lower portions of the middle top beams, and longitudinal moving guide bars are mounted on the bracket and sleeved with the corresponding longitudinal moving guide sleeves. The longitudinal push oil cylinder is arranged between the middle top beams and the bracket, and drives the middle top beams and the bracket to slide longitudinally and relatively. The suspension type hydraulic support is characterized in that connecting beams I are arranged at extension ends of the two middle top beams, the length of each connecting beam I is equal to the distance between the two external top beams, and the middle top beam support columns support two ends of each connecting beam I; connecting beams II are arranged at retraction ends of the two middle top beams. The suspension type hydraulic support is higher in structural strength, convenient to mount and transport, and convenient for coping with various complicated supporting surfaces so as to perform effective support.
Description
Technical field
The present invention relates to a kind of mining equiment, be specifically related to the termination suspension-movable hydraulic support of a kind of coal mine support coal mining or stope.
Background technology
Under coal mine, the intersection of coal-face and stope drift active workings is called termination, for the supporting at position, termination, is called end support.Position, termination is the joint of the equipment such as drag conveyor and elevating conveyor, is again the throat of walkway, ventilation, haul and defeated coal.The quality of end support, is the key point that determines that can work plane normally move, and according to relevant security department statistics, the human casualty accident occurring at position, termination accounts for the over half of down-hole accident.As the end support mode that adopts hydraulic prop to add back timber composition at conventional face is carried out supporting, the poor safety performance of supporting, labor strength is large, and support work efficiency is low.
The applicant applies for and obtains major path termination suspension moving hydraulic support > > under Patent right < < coal mine and " authorize publication number 20313013U " for 2013, between outside back timber and middle part back timber, can conveniently move, make passage broad, reduce labour intensity, improve security performance, reduce the generation of dangerous accident.After throwing in use, enjoy great popularity, obtained good economic benefit and social benefit.But also there is following unsatisfactory place:
1, two middle back timber pillars are positioned in the middle of two outside back timber pillars, and back timber prop density is large, has dwindled channel width, takies installation, the transport channel of the equipment such as drag conveyor and elevating conveyor.
2, cantilever support is fixed overall structure, to underground transportation, installs and brings difficulty.
3, cantilever support can not transverse shifting, brings difficulty to the supporting at position, termination.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of broad, safe, the efficient coal mine roadway of passage termination suspension-movable hydraulic support that has, outer back timber pillar, middle back timber strut width are consistent, expand the width of the passage of knowing clearly, and facilitate installation, the transportation of equipment.
The present invention is achieved through the following technical solutions: a kind of coal mine roadway termination suspension-movable hydraulic support, it comprises: outside back timber, middle part back timber, outer back timber pillar, middle back timber pillar, bracket and longitudinally pass oil cylinder.Described outside back timber is two, outer back timber shore supports for the two ends of outside back timber.Described middle part back timber is two, back timber shore supports in the two ends use of middle part back timber.The bottom of middle part back timber arranges bracket, and described bracket is rectangular frame; Bracket is connected with middle part back timber by bracket suspension assembly.Vertical shift fairlead is installed in described back timber bottom, middle part, and vertical shift guide peg is installed on described bracket, and described vertical shift guide peg is sleeved in vertical shift fairlead.Between middle part back timber and bracket, longitudinal passing oil cylinder is set, longitudinally passes longitudinal sliding motion between hydraulic oil cylinder driving middle part back timber and bracket.It is characterized in that: the external part of described two middle part back timbers arranges tie-beam I, the length of described tie-beam I equates with the distance between two outside back timbers, and middle back timber shore supports is at the two ends of tie-beam I; Two middle part back timber indentation ends arrange tie-beam II.
Described outside back timber middle part connects by traversing fairlead, and described traversing fairlead is two, and traversing fairlead two ends are fixed on the lower end of outside back timber; Traversing guide peg is installed at described bracket two ends, and described traversing guide peg is sleeved in traversing fairlead.Horizontal passing oil cylinder is set between traversing fairlead and bracket, laterally passes hydraulic oil cylinder driving bracket horizontal sliding in traversing fairlead.
Described traversing fairlead and traversing guide peg leave gap in the horizontal direction.
Back timber shore supports in using in the middle part of described tie-beam II.
Described back timber two ends, middle part are fitted in respectively the upper end of tie-beam I and tie-beam II.
The invention has the beneficial effects as follows:
1, conveniently moving, quick between outside back timber and middle part back timber.Significantly reduce workman's labour intensity, improved security performance, reduced the generation of dangerous accident.
2, the support middle part middle back timber pillar of back timber and the outer back timber strut width of supports outer back timber are equally large, have increased channel width, more convenient elevating conveyor transportation and installation, and production efficiency is high to be increased substantially.
3, middle part back timber can transverse shifting, again can left and right skew, and a mask of being convenient to tackle various complexity effectively supports.
4, the connected mode between two outside back timbers and two middle part back timbers, the intensity of raising structure, is convenient to install and transportation.
